Need help! Cables & Lace Broomstick Hat by Kristin Omdahl

Has anyone made the Cables & Lace Broomstick Hat by Kristin Omdahl (from the book Crochet So Fine, and I see it was offered as a free pattern here on Knitting Daily)?

If so, did the Cable Band Pattern work for you as written? I have been trying to work on it several times today, but my cable does not look like the one in the photo. I seem to get the X where the cable crosses over, but the rows on either side do not seem to continue the pattern, with some stiches coming to the front and others going to the rear. Instead, 4-6 each have you do all stitches in either bpdc or fpdc, which creates a straight line.

This is the first time I've done cable work, so I could be doing it wrong, but I've followed the written pattern carefully and examined the stitch diagram closely.
